Impairment of host cell ribonucleic acid polymerase II after infection with frog virus 3.
Evidence is presented that, in frog virus 3-infected BHK cells, inhibition of ribonucleic acid (RNA) synthesis is paralleled by a decreased activity of host cell RNA polymerase II, while the template ability of host cell nuclei and chromatin is unaffected.

Ferritin H and L mRNAs in human neoplastic tissues.
The typical tissue isoferritin pattern varies during neoplastic transformation, usually shifting toward a more acidic profile. To investigate the molecular basis of this phenomenon, we have analyzed the steady-state levels of the H and L mRNAs in several neoplastic tissues. By using specific probes for the two ferritin subunits, we have found, in three different adenocarcinomas and in a case of Hodgkin lymphoma, a two- to four-fold increase of the H and L mRNA levels compared to those found in normal human liver.

[Renal cell carcinoma. Significance of prognostic factors & current treatment].
The Authors carried out a literature review on prognostic factors and current management of renal cell carcinoma. A significant factor influencing survival appears to be the extension of the primary tumor (T). The finding of no nodal involvement is not always a favourable prognostic factor if the tumor is no more confined. A perfect knowledge of the prognostic factors may be useful to identify those patients who need post-operative chemotherapy. Surgery is still the treatment of choice for renal cell carcinoma. Extensive lymphadenectomy does not influence long-term survival, nevertheless since there is no additional mortality or morbidity, it is considered useful for a correct staging and a better evaluation of long-term prognosis.
